Internally we have a lint that surfaces this as a warning. Googlers, please refer to go/al-rule/NarrowingConversion.

Related: b/309552840

When we do:

coords.toolMajor = (float) (double) coordsList.get(3) * density;

coordsList.get(3) is casted to a double, then a float, before the multiplication happens.

I don't think this is intentional. The intention of the code here seems to be:

  • Cast to a double: coordsList is a List<Object> so the cast narrows the value
  • Cast to a float: To fit the resulting value into coords.toolMajor, which is a float.

As such, add parenthesis to address this.

It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption to this rule, contact Hixie or stuartmorgan on the #hackers channel in Chat (don't just cc them here, they won't see it! Use Discord!).

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing.
